Low Power Quad Operational Amplifiers

LM124A/LM124QML Low Power Quad Operational Amplifiers

January 2005

General Description

The LM124/124A consists of four independent, high gain,
internally frequency compensated operational amplifiers
which were designed specifically to operate from a single
power supply over a wide range of voltages. Operation from
split power supplies is also possible and the low power
supply current drain is independent of the magnitude of the
power supply voltage.

Application areas include transducer amplifiers, DC gain
blocks and all the conventional op amp circuits which now
can be more easily implemented in single power supply
systems. For example, the LM124/124A can be directly op­erated off of the standard +5Vdc power supply voltage which
is used in digital systems and will easily provide the required
interface electronics without requiring the additional +15Vdc
power supplies.

Unique Characteristics

n In the linear mode the input common-mode voltage

range includes ground and the output voltage can also
swing to ground, even though operated from only a
single power supply voltage

n The unity gain cross frequency is temperature

compensated

n The input bias current is also temperature compensated

Advantages

n Eliminates need for dual supplies
n Four internally compensated op amps in a single

package

n Allows directly sensing near GND and V

to GND

n Compatible with all forms of logic
n Power drain suitable for battery operation

OUT

Features

n Internally frequency compensated for unity gain
n Large DC voltage gain 100 dB
n Wide bandwidth (unity gain) 1 MHz

(temperature compensated)

n Wide power supply range:

Single supply 3V to 32V
or dual supplies

n Very low supply current drain (700 µA) — essentially

independent of supply voltage

n Low input biasing current 45 nA

(temperature compensated)

n Low input offset voltage 2 mV

and offset current: 5 nA

n Input common-mode voltage range includes ground
n Differential input voltage range equal to the power

supply voltage

n Large output voltage swing 0V to V

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed
specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test
conditions.

Note 2: The maximum power dissipation must be derated at elevated temperatures and is dictated by Tjmax (maximum junction temperature), ThetaJA (package
junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is Pdmax = (Tjmax ­TA)/ThetaJA or the number given in the Absolute Maximum Ratings, whichever is lower.

Note 3: Short circuits from the output to V+ can cause excessive heating and eventual destruction. When considering short circuits to ground, the maximum output
current is approximately 40mAindependent of the magnitude of V+. At values of supply voltage in excess of +15Vdc, continuous short-circuits can exceed the power
dissipation ratings and cause eventual destruction. Destructive dissipation can result from simultaneous shorts on all amplifiers.

Note 4: This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP
transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is also lateral NPN parasitic transistor action
on the IC chip. This transistor action can cause the output voltages of the op amps to go to the V+ voltage level (or to ground for a large overdrive) for the time
duration that an input is driven negative. This is not destructive and normal output states will re-establish when the input voltage, which was negative, again returns
to a value greater than -0.3Vdc (at 25 C).
